Application filed November-6, 1920. Serial No. 422,282.

To all whom it may concern:

Be it known that I, ABRAM S. KIRSHNER, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Processes of and Apparatus for Extracting Oil, of which. the following is a specification.

This invention relates to a processof and apparatus for extracting liquid from any material such, for example, as cotton seed, and the object of the invention is'a process of accomplishing this by acting upon the material by pressure, preferably hydraulic, and also subjecting the material to the "ac tion of centrifugal force so that the material is crushed and compacted by pressure and the liquid thrown therefrom centrifugally. The invention also relates to apparatus by which this process may be simply executed.

In the preferred embodiment, the material, such as cotton seed, is subjected to the quick and rapid blows successively delivered by hydraulic means while thematerial is also acted upon by centrifugal force created, for example, by the rapid rotation of the parts carrying the material being treated.

In the drawings accompanying and forming part hereof which show one form of apparatus for carrying out my process:

Figure 1 is a perspective view of a structure made in accordance with my invention. Figure 2 is a vertical central section .of the same.

Figure 2 is a side elevation of a valve mechanism.

Figure 3 is a horizontal the line 3-3 of Figure 2.

Figure 4 is a sectional detail of several of the parts which, in the drawing, are shown section through before they are assembled in order that the construction of the parts may be better seen. Figure 5 is a detailshowing the same parts assembled.

. Referring now to the details of the drawings by numerals:- 1 designates an outside casing which may be of any desired form but is shown in the drawing as a casting havin a support 2, the upper part being provi ed with two main chambers 4 and 5, one adapted to have the oil thrown intoit and the other a chamber to receive the dried material from which the liquid has been exthrough which the extracted liquid may pass, and the chamber 5 having a downwardly inclined chute 8 terminating in a spout 9 from which the dried material may pass from the machine. The upper part of the chamber 4 is provided with a head 12 having a hopper 14 by which the material to be treated is passed into the machine.

In the embodiment shown in my drawing, the main casting is also formed with an integral support as that shown at 15 for a bearing socket 16, the latter having bearings 18 and 20 for a tubular shaft 22, the latter being driven by any convenient means such as the belt '24 and pulley 26. The lower end of the tubular shaft 22 passes into a stuffing box to which fluid power may-be delivered by means of a pipe as 32 shown inFigure 2 which is connected to a valve us that shown at 33 in Fi supply pipe being shown at 33*. aid valve is operated by a cam as 33* so that'at each rotation of the cam the machine is operated to allow the fluid pressure to charge and discharge from said pipe 32; thus the valve is designed to be opened and closed in rapid succession so that the fluid means will perform its work intermittently. The main casting 1' is further provided with a third or central chamber 36 to form a housing for the aforesaid tubular shaft 22, and also to afford a support for the bearings for the upper part of this shaft. To that end, the tubular shaft 22 passes entirely through the chamber 36 and is preferably screwed into one of the main members of my press designated by the numeral 40. This is directly under the hopper 14 and on its upper side-is provided with a deep recess 42 to oontainthe plunger or piston 44, the latter also having arecess 46 in its upper surface to receive the material from the hopper. This member is also provided with a downwardly projecting tubular cenre 2. a'

member 40 with the usual screening operated it is part of from and into the deep recess 42 thereby forcing the plunger or piston 44 upward, the latter being provided with a packing ring 54 to make the same tight. The plunger or piston 44 is provided with means, as the bolt 56 and spring 58, to permit the fluid pressure to force the plunger or piston 44 upward away from themember 40 of the tubular part, the spring 58 being arranged to return the parts to the normal positions shown in Figure 2 as soon as the fluid pressure is released. Located over the member 40 is the second principal part of my aparatus which consists of an annular member 60, having a downwardly inclined portion 62, which member 60 is bolted to the member 40 so as to leave a chamber 63 between the two parts 40 and 62. The member 60 is provided with a projecting annular bib 64, shown in Figure 2, and the plunger or piston 44 is intended to have 1ts upper part projected into the space left by this bib so as to crush the material, as will be hereinafter explained. The inclined wall 62 is provided with a-series of openings 68 and the inner surface of this wall is provided or hairoloth covering 70. The parts 40 and 60 are bolted together by means of bolts 7 2 and nuts 74 so that these parts are always maintained the proper distance apart and are compelled to rotate together. When the machine 1s first desirable to close the lower the chamber 63 between the parts 40 and 62 and for this purpose I provide a disk or plate 80 provided with an upward flange 82 which is designed to be moved up and down to open the close the bottom of the aforesaid aperture 63. This plate 80 and its flange 82 are supported by a flange 86 formed on and projecting upwardly from a gear wheel 88. This gear wheel 88 is internally threaded to screw onto a screw threaded flange 9O projecting upwardly from the housing of the bearings 5O. If this gear wheel 88 is rotated in one direction, it will cause the disk or plate and its flange 82 to ride upward to close the'opening of the chamber 63 or, if rotated, in the opposite direction, it will move said disk or plate 80 and its flange downward to open the mouth of said chamber 63. In order that the parts may be operated from the exterior of the machine I provide a shaft 92 having a worm 94 (see Figure 3) which meshes with the aforesaid gear wheel 88, the said shaft 92 having a hand wheel 96 on the exterior of the machine by which said shaft may be rotated in one direction or the other.

The operation of my device is asfollows: When the machine is first operated, the attendant rotates the hand wheel 96 toturn the worm 94 and rotate the gear 88 so as to elevate the disk or plate 80 and its flange 82 to close the mouth of the cber 63..

eas es Then the material tobe acted upon is fed into the hopper 14. The material of course falls through said hopper into the recess in the piston or plunger 44 and as these parts are being rotated at' a very high speed by means of the belt 24 and the pulley 26, the said material is thrown outwardly by centrifugal force, passing over the flange of the piston or plunger 44. While said piston and its connected parts are being rotated at high speed, the flllld pressure acts upon the under surface of said piston 44 and rapidly propels it upward into the space around the annular bib 64 crushing the material therebetween. As the valve is arranged to be opened and closed with considerable rapidity, the said piston 44 is forced upward and then the spring 58 forces the piston back during which time the parts are rapidly rotating to affect the liquid centrifugally and expel it through the openings 68. After the parts are thus simultaneously rotated and reciprocated until the operator finds that the chamber 63 is filled, he then rotates the hand wheel 96 to lower the flange 82 on the disk or plate 80 so as to open the mouth of the chamber 63. The operation of the machine will now cause the dry material to be ejected from thechamber 63 by centrifugal force and into the chamber 5 from which'it passes through the chute 9 into any suitable receptacle. During the time it takes for the material to pass from the deep recess in the piston or plunger 46 out through the chamber 63, during which time it will be understood that the piston is given rapid reciprocations against the member 60, there will be ample time for the liquid to be expelled centrifugally from the meal or other material through the openings 68, before the dried cake reaches the mouth of the chamber 63 from which it is expelled.

It will be obvious that changes and modifications may be made in the form and construction of my apparatus without departing from the invention, and therefore reference should be made to the appended claims to determine the scope thereof.
